# rmtolamatchtypevalue

This code list is used in association with the Match Type attribute which is present within the Royal Mail Address Feature Type. The Royal Mail Address provides Royal Mail delivery point addresses, a point geometry and information describing the relationship they have with Local Authority addresses. The code list describes the relationship between the Royal Mail Unique Delivery Point Reference Number (UDPRN) and the Unique Property Reference Number (UPRN) of an address.

| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Direct    | The Royal Mail Unique Delivery Point Reference Number (UDPRN) has been matched directly to a Unique Property Reference Number (UPRN), either in a one-to-one or many-to-one relationship (many UDPRNs to one UPRN).                                                                  |
| Neighbour | The Royal Mail Unique Delivery Point Reference Number (UDPRN) cannot be matched directly to a Unique Property Reference Number (UPRN), but there is sufficient information in the Royal Mail data description to identify a UPRN which can reasonably be expected to be a neighbour. |
| Parent    | The Royal Mail Unique Delivery Point Reference Number (UDPRN) cannot be matched directly to a Unique Property Reference Number (UPRN), but there is information in the Royal Mail data description which indicates the record is a subdivision of an existing Parent UPRN.           |
| Street    | The Royal Mail Unique Delivery Point Reference Number (UDPRN) does not meet the criteria for Direct, Parent or Neighbour matches, but there are other Unique Property Reference Numbers (UPRNs) which exist on the same street.                                                      |
| Unmatched | The Royal Mail Unique Delivery Point Reference Number (UDPRN) cannot be matched to a Unique Property Reference Number (UPRN).                                                                                                                                                        |
